Description

Technical Field

[0001] The utility model relates to the technical field of air filtration, in particular to an air filtration circulation device. Background Art

[0002] In the aluminum foil processing industry, pulverizers are important production equipment and are widely used in the crushing process of aluminum foil. However, when pulverizing aluminum foil, a large amount of debris and dust will be generated. These dust particles are tiny and easily dispersed in the air, which not only seriously pollutes the working environment, but also poses a potential threat to the health of operators. Long-term inhalation of these dusts may cause respiratory diseases and other health problems.

[0003] Traditional dust treatment is mainly achieved by installing air filtration equipment around processing machines. These devices usually try to separate and filter dust particles from the air by continuously extracting and filtering the surrounding air. However, this traditional filtration method has many shortcomings.

[0004] First, traditional air filtration devices can only partially improve air quality and are difficult to effectively capture and remove fine dust particles in the air, resulting in low overall filtration efficiency. Second, even if air filtration equipment is installed, due to the diffusion of dust and the limitations of the equipment, workers still need to wear personal protective equipment such as masks at the work site, which not only increases the inconvenience of operation, but also fails to fundamentally solve the problem of dust pollution.

[0011] Furthermore, in order to realize the detachable and replaceable dust bag, the dust bag is sealed and sleeved on the top of the exhaust pipe through a rubber sleeve.

[0012] Furthermore, in order to facilitate the replacement of the dust removal bag in the sealing cover, a protective door is rotatably installed on one side of the surface of the sealing cover.
